A newly-wed couple wake up on the first morning of the their honeymoon in the Caribbean and decide to take a stroll down the beach. On their way they pass a shanty house, and sitting on the front porch is an overweight woman, stark naked, legs akimbo, eating a slice of watermelon. The husband sees this and liking the idea of his new wife exhibiting her body in public asks her whether she would do the same. The wife looks at him in disgust and refuses.
The second morning they pass the shanty house again and, sure enough, the overweight woman is sitting on the porch stark naked, legs akimbo, eating another slice of watermelon. Not being put off be his new wife's refusal, the husband enquires of his wife, "Why don't you go over and ask that woman what it feels like to sit there naked, letting the air waft over your cunt?". The wife again refuses.
This continues each morning for two weeks until it is the last day of the honeymoon. Each morning they would pass by the woman, each morning the husband would try to persuade his new wife to copy her, and each morning the wife would refuse. However, it being the last morning the husband gives it one more try and enquires of his wife, "Why don't you go over and ask that woman what it feels like to sit there naked, letting the air waft over your cunt?"
The wife finally gives in, opens the gate of the shanty house and walks up to the overweight woman on the front porch. "What does it feel like to sit there naked, letting the air waft over your cunt?" she asks, hesitantly. "I don't rightly know", replies the woman, "but it sure keeps the flies off me an' my watermelon."
